Edgar Allan Poes The Premature Burial :: essays research papers

The Mind vs. the Undead The Romantic Era was a time when writers wrote with passion in relation to elements of writing such as the fantastic or supernatural, the improbable, the sentimental, and the horrifying. Edgar Allan Poe was one of the many writers who used elements such as these in his writings. Poe was famous for reflecting the dark aspects of his mind in a story, creating detailed imagery intriguing the reader. The fantastic and supernatural elements are expressed in The Premature Burial as impossible and in a sense, horrifying. The idea of people walking after their believed death is very extreme thinking in a world that seems normal.   Ã‚  Ã‚  Ã‚  Ã‚  The writing style of Edgar Allan Poe shows the writer to be of a dark nature. In this story, he focuses on his fascination of being buried alive. He quotes, â€Å"To be buried alive is, beyond question, the most terrific of these [ghastly] extremes which has ever fallen to the lot of mere mortality.† page 58 paragraph 3. The dark nature is reflected in this quote, showing the supernatural side of Poe which is reflected in his writing and is also a characteristic of Romanticism. Poe uses much detail, as shown in this passage, â€Å"The face assumed the usual pinched and sunken outline. The lips were of the usual marble pallor. The eyes were lusterless. There was no warmth. Pulsation had ceased. For three days the body was preserved unburied, during which it had acquired a stony rigidity.† page 59 paragraph 2. The descriptive nature of this writing paints a vivid picture that intrigues the reader to use their imagination and visualize the scene present ed in the text. This use of imagery ties with aspects of Romanticism because of the nature of the descriptions Poe uses. Describing the physical features of one who seems dead is a horrifying perspective as not many people thing about the aspects of death.   Ã‚  Ã‚  Ã‚  Ã‚  The mind is a very powerful tool when it is exploited to think about situations out of the ordinary. Describing in vivid detail the conditions of one after his, her, or its death associates the mind to a world that is filled with horrific elements of a dark nature.

Modern Means of Communication Have Introduced Relevant Changes in Our Lives

As humans have a highly developed brain, new innovations in communication are created to make our living standards better. However, there has been a debate on whether such changes benefit our lives more than worsening them. In this essay, I will point out both side of view and state what I think. In this modern world, telephones are no longer the only device used to communicate with other people. For example, using new software applications like skype, is undoubtedly one of the popular ways for communication.In this way, we can surf the net and chat with our friends at the same time. Time can be more well-spent and furthermore, extra phone bills can be saved as well. Another advantage for communicating via electronic devices is convenience. For those who cannot bother going outdoors to meet up with someone, such modern technology can certainly solve their dilemma. On the contrary, others suggest that such trend of communication can make people’s social skills degenerate.As tim e passes, people tend to forget how to talk to each other naturally when it comes to the necessity of face-to-face communication. In addition, such phenomenon can increase the popularity of laziness in one’s habit. To sum up, I would admit the fact that modern means of communication can add unexpected good points to our social lives. Thus, the downsides cannot be ignored. It would be better if we remind ourselves to go out with others once in a while to regain the confidence we used to have in our social lives.

Isaac Newton s Theory Of Motion And Universal Gravitation

When I hear about a novel on Isaac Newton, I picture a massive textbook with highly scientific language, which is very difficult to read and understand. Well renowned writer James Gleick provides us with an alternative view of Isaac Newton, which is enjoyable to read and directed towards a lay audience. In his writing, James Glick is concerned with how certain scientific laws, such as the laws of gravity, change the way we understand the material world. He is known for his specialty in writing for a lay audience, instead of a purely academic crowd. In this book, Gleick provides us with a very non-scientific, conversational description of Isaac Newton and his works. Even though this book is targeted at a general audience, it has over sixty pages of notes and it is still be considered as an academic piece that provides us with an unconventional understanding of Isaac Newton and his contributions to science. James Gleick provides us with a basic view of Isaac Newton and how his works influenced the scientific world though his laws of motion and universal gravitation. His main goal was to provide us with a more human understanding of this great scientist, which we do not see represented in textbooks and other specialized bibliographies. He does this by discussing some of Isaac Newton’s letters and unpublished books. Before reading this book, I thought of Isaac Newton as a divine scientist who was flawless.
